  1. Main research contents and achievements of this thesis is as follows : l. this paper carries through particular test and analysis to the basic physical - chemical properties of gaojiawang palygorskite, an environmental mineral fibre, by xay, ir, tem, sem etc. this paper has also discoursed upon the development appliance research status in quo and directions of palygorskite. 2. according to the preceding surface modification research achievements to nonmetal mineral materials, the author combines the self characteristics of palygorskite such as the ratio of length and diameter, typical nano - rank particle diameter, big ratio surface area, well - developed crystal growth imperfection and lattice defect etc. the author also designs organising modification ortho - experimentation of palygorskite by adopting iso - propyl alcohol as thinner of wd - 51 and ndz - 401, and acquires the best craft parameters and craft conditions for gaojiawang palygorskite original ore organising modification, namely : wd - 51 concentration 1. 6 % ( wt % ), modification temperature 120 ?, and modification time 60 mins ; ndz - 401 concentration 2. 0 % ( wt % ), c modification temperature 120, modification time 80 mins

    在前人對非物材料表面改性的基礎上,結合環境物纖維?坡縷自身的特點(如:長徑比、典型的納米粒徑、大比表面積、發育的晶體生長缺陷和晶格缺陷等) ,通過對坡縷機化改性設計正交試驗,採用( ch _ 3 ) _ 2choh作為釋劑,獲得了採用wd - 51和ndz - 401對高家窪坡縷進行機化改性的最佳工藝參數和工藝條件,分別為: wd - 51的濃度為1 . 6 ( wt ) ,改性溫度為120 ,改性時間為60min ; ndz - 401的濃度為2 . 0 ( wt ) ,改性溫度為120 ,改性時間為80min 。
